Hi a9302031972bnkp, welcome to Thunkable! 
Be sure to check out How to ask Great Questions v2.0, the Community Guidelines, and our Getting Started Guide to make the best of your Thunkable Community experience!
AIA files are not available via Thunkable. Our Community is a place for our Creators to work together in solving issues and sharing ideas. For the best results, you’ll want to start work on your project first and then ask specific questions if you run into them. You will be unlikely to get much help asking someone to help you without offering any specifics.
